  1. 1. Reduction of Crosstalk Distortion in 5G

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Ali Al-Qamaji; Fida Abdalrahman; [2019]
    Nyckelord :Wireless Communication; Power Amplifier; Linearization; Digital predisposition; 5G; Massive MIMO.; Technology and Engineering;

    Sammanfattning : Increasing demand for higher data rates in wireless communication systems has tremendously evolved over the last years. This demand is rapidly increasing with rising in number of wireless devices. LÄS MER

  3. 2. Precoding in MIMO, OFDM to reduce PAPR (Peak to Average Power Ratio)

    Master-uppsats, Institutionen för datavetenskap, fysik och matematik, DFM

    Författare :Muhammad Irfan Ishaq; Yasir Ali Khan; Muhammad Talha Gul; [2012]
    Nyckelord :Peak to Average Power Ratio;

    Sammanfattning : One of the critical issues of systems utilizing Orthogonal Frequency Division Multiplexing (OFDM) is the high peak to the average power ratio of OFDM signals. We have used Precoding as a way to mitigate the PAPR problem. Furthermore the performance of Precoded OFDM in fading multi-path channels has been studied. LÄS MER

  5. 4. Evaluation of Precoder Designs Using Measured MIMO Channels

    Master-uppsats, KTH/Signalbehandling

    Författare :Ali Alenezi; [2011]
    Nyckelord :;

    Sammanfattning : MIMO transceiver designs rely mainly on the knowledge of channel state information (CSI) at the transmitter and receiver sides of a communication link. In most  practical scenarios due to the fast fading channels, the transmitter side can only have statistical (or long-term) information about the channel. LÄS MER

  7. 5. PERFORMANCE ANALYSIS OF MULTIPLE ANTENNA TECHNIQUES IN WiMAX

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Yousaf Ali Shah; [2010]
    Nyckelord :WiMAX; Capacity Analysis; STBC; MIMO; SFBC;

    Sammanfattning : The modern wireless systems are required to have high voice quality and data rate. Since our concern is most with cattering environment, antenna diversity is a practically effective and widely applied technique to reduce the effect of multipath fading. LÄS MER
